With Sandboxie you can run multiple instances of pretty much any program and indeed MS Powerpoint. Of course there's much more to Sandboxie than that :)
When Sandboxie is installed, simply right-click on the Powerpoint executable (POWERPNT.EXE) or a shortcut you have created. it will not work with the default MS Office shortcuts! (the reason for that is probably related to this question i posted a few weeks ago) and select Run sandboxed, this will start Powerpoint inside the sandbox (virtualized).
Here's a screenshot with 3 sandboxed Powerpoint 2003 sessions (it will most certainly work with with PPT 07), you can see the titlebar # # indicating that a program is running sandboxed, the top window was started normally.
Note: if you make changes and want to save a document inside a sandbox, make sure to recover the document before deleting the sandbox (or save the file at a location wich is listed for Quick Recovery in the sandbox settings and you will be prompted for recovery immediately).
With the registered version, you can create multiple sandboxes (only 1 with the unregistered version), if you need more than 2 instances.
As a neat bonus, Sandboxie will greatly add to your security when you run the web browser inside a sandbox. benefits of the registered version: force programs to run inside the sandbox, create multiple sandboxes, you may install sandbox on as many computers as you own with a single license.
Note: Sandboxie is not available for Windows 64-bit.
The behavior is buried in the "Crop" ribbon menu. When you place a photo in most containers in PowerPoint 2010+ (I believe, definitely 2013 and 2016), the default is to "Fill" as much container as possible, cropping stuff that doesn't fit the aspect ratio of the container.
Change to "Fit" to fit all of the image in the container at all times, leaving white space where it does not fill excess space.
Click the down arrow below "Crop" on the ribbon/toolbar, and the two selections are at the bottom.

Change the default printer to other printer (either the standard XPS printer or any other). This is because for inexplicable reason, PowerPoint (the only non-print oriented Office app) utilize something from the default printer driver info for rendering the font. On old printer (think dot-matrix old) it's incompatible with the newer PowerPoint.
